loader `for_gem` in rspec

I am writing a gem and have it structured in the conventional way:

lib/
|- gem_name/
|   |- ...
|- gem_name.rb

Inside gem_name.rb I am using

loader = Zeitwerk::Loader.for_gem
loader.setup

This works fine when I build, install and use the gem. However, when I use it in a unit test in RSpec, it shows me uninitialized constant, even when I require_relative ../lib/gem_name.rb from spec/spec_helper.rb.

I don't understand, why isnt the GemName namespace in the LOAD_PATH

fxn commented

RSpec adds lib to $LOAD_PATH automatically, it should be enough to do

require "gem_name"

in spec/spec_helper.rb. Does that work in your project?

Yes it did work I was totally looking in the wrong place. Sorry to waste your time like this. Thank you for the help

This project does not have RSpec set up as documented in the RSpec README, and because of that spec/spec_helper.rb is not being loaded.

Please have a look at the "Setup" section of https://github.com/rspec/rspec-metagem.
